Brett,
The Motorola C650 is a USB Communications Device Class (CDC) device and
as such the Apple supplied CDC driver (ApplUSBCDCDriver) has matched
the device and published the /dev/cu.usbmodem1B1 entry. As you have
discovered any application, like minicom, that knows how to talk with a
serial device can use it.
What specifically are you trying to do with the phone?

Hello,
I'm having an issue with an application that is trying to talk to a
Motorola cellphone. FYI the app uses libusb. The problem arises when
doing USBDeviceOpenSeize. It returns kIOReturnExclusiveAccess.
Classic is not running. I'm running 10.3.8.
Using USB prober, I see:
3.110 [5] Finding device driver for Motorola Phone (C650), matching
personality using com.apple.driver.InternalUSBModem, score: 59000
4.001 [5] Finding device driver for Motorola Phone (C650), matching
personality using com.apple.driver.AppleUSBCDCEthernet, score: 60000
4.002 [5] Finding device driver for Motorola Phone (C650), matching
personality using com.apple.driver.AppleUSBCDCDriver, score: 60000
I don't know that it helps, but I can use minicom pointed at
/dev/cu.usbmodem1B1. I was able to give it an atdt followed by my
land line number, and the land line rang. The phone also indicated
that it was calling me.
Any thoughts?
Thanks,
Brett
